So, will the Leaning Tower of Pisa ever fall over? The Tower has been falling ever so slightly through the centuries and reached a tilt of 5.5 degrees in 1990. Additionally, multiple engineering projects have been undertaken to keep the structure standing while preserving its signature slant. Now, experts predict that the latest measures taken to stabilize the historical bell tower are enough to keep it standing, though still slanted, for centuries to come.

According to Smithsonian Magazine, the latest effort, which was completed in 2001, saw engineers successfully reduce the southward slant to an angle of four degrees. The BBC notes the feat was achieved by first fixing lead weights to the north side and removing soil beneath the north side to bring the Tower to a more vertical position.

In fact, a British engineer who helped lead the Tower’s stabilization project, John Burland, an emeritus professor of civil and environmental engineering at the Imperial College of London, said the team predicts that the northward movement they initiated will stop in a few years, and the Tower will eventually return to its slow slant to the south. However, he’s confident that the Leaning Tower of Pisa will remain standing unless a strong earthquake, or other disaster, causes a major shift to the foundation that could make it fall.
